Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed September 30. .1907. Serial No. 395,107.

To all whom it may concern:

Be it known that I, Gnonon L. Horriux, u

citizen of the United States,

residing at Hamilton, Butler county,

Ohio, have in-I vented a new and useful Im rovement in Riding-Plows, of w 1 h the ollowing is a specification.

My invention relates to riding plows, and i the objects of my improvement are to provide automatic eral movement of the seat when is thrown out of the ground by an obstruction; to provide automatic means for maintaining the land wheel in contact with the different vertical positions of the plow; to provide such construction and assemblage of parts as will lessen the draft, will cause the plow to pass obstructions with greater facility and less danger of being bro'cen, and as will prevent any extreme and sudden lateral movement of the seat whcrcbv the operator might be thrown or injured. These objects are attained in the following described manner, as illustrated in the accompanying drawings, in which Figure 1 is a plan of a iiding plow embodying my improvements; Fig. 2, a side elevation; Fig. 3 asrear elevation Fig, l a detail of construction showing parts in vertical section on the line of the land wheel axle and Fig. 5, a section on the line a---a of Fig. 1.

In the drawings, 1 represents the housin formed with a slot 2, 3 a short ole or bite which is pivotally secured t ere-to. The front axle 4 is formed with a vertical hearing 5 and with a vertical bracket 6 which terminates in a segmental rack 7. Said axle is longitudinally adjustable .in the housing by means of a bolv in slot. 2. The front spindle \vhereon the front furrow wheel 9 is journaled is turned at an obtuse angle and swivelod in bearing 5. A detent lever 11 t'ulcrumed on bracket 6 cooperates with rack 7 and is connected with spindle 8 by means of a link 12 for moving and maintaining the spindle with the wheel 9 in different vertical positions in relation to the axle 4. A bar 13 projects in a forward direction from spindle is adjustably connected 8 and a brace 1 thereto and to the hitch 3 for automaticall the spindle Wit moving and mainlainin the wheel 9 in a direction substantially parallel with that of the hitch.

A front beam 15 formed with an obtuse means for lessening the latthe plow l l l a L r t t t t r t t I,

f angle is secured to the housing,

and a rear beam 16 formed with a similar angle is secured thereto by means of a bracket 17 Said bracket is formed of two members pivot ally connected to ether by means of a bolt. or pintle 18 where y they may be adjusted with the beams in different horizontal un les in relation to each other and maintained in adjusted position by means of a pin or clamping bolt it) being inserted through holes formed through the members of the market.

COIICEH'O4IOJIVUX disks 21 are rotatively secured to the respective beams by means of brackets and spindles J2 and 23- in the usual manner. It sleeve 21 provided with a sog; mental rack 25 is secured on. the rear beam 1t and a crank spindle 26 provided with the land wheel :57 is journaled therein. A detent lever 38 secured on said spindle cooperates with said rack and serves to rotatively more and maintain said spindle with wheel 27 in different vertical positions. A rear extension 29 of beam 16 connected thereto by means of a hinge joint 30 is formed with a horizontal arm 31, with a vertical bearing 32 and with a stop 33. rear spindle 34 provid-wl with the rear caster or furrow wheel 35 is turned at an angle and swiveled in said bearing 32 wherein its niovmnent with the wheel 35 in a. forward direction is limited by contact. with the stop 33. The seat bar 36 provided with the operators seat 37 and with the foot rest $38 is secured to and supported by the arm ilhot the hinged member 29.

A coiled spring 41 is pivot one end in arm 31 and adjustably secured at the other end in an arm or lug 4.2 which projects laterally from the rear beam 16 at a point near the angle therein. Said spring serves to maintain the hinged member 29 under :1 yielding pressure in its normal closed position and in the Fine of beam 16.

A coiled spring 43 ailiustably secured at one end to the foot rest 38 and secured at the other end to the detent lever 28 reinforces the action of spring 4-1 in maintaining member 29 in the closed position and serves also to yioldinglv actuate the lever 28 in a rearward direction for maintaining the land wheel 27 in continuous contact. with the ground. link or clevis ll. swivcled on the end of the detent lever 28 serves to lock the detent 45 thereon out of engagement with ally secured at the segmental rack shown in Fig. t.

In operation. when the detent la is held out of engagement with the rack 2-3 the exertion of the nprinn 4 on lever 28 pet-nuts the disks to ride over an obstruction or through hard jlltlt'tS in the oil without lilting the land wheel, thereby making the draft more ltJllr-dtllll and murh easier on the team. \v'hen either of the disks nlllltt'h a permanent olelruetion. as a concealed rook, they are lifted and quickly thrown laterally in the direction of the land wheel. Where the seat is rigidly secured to the 2.3 when desired, as

i to move and beam, this alltlLlQll movement throws the seal laterally so far that the operator is thrown to the ground with danger of injury and of the escape of the t -am. The hinge. joint in the beam ()bVlillQ-i this danger by being; automatically opened under an} sudden movement of the (ll l{\' with the beams toward the land wheel. while the seat is permitted to remain in substantially the *annpo i1ion. After the. obstruction is passed the spring ll FCI'W; to automatirally and quit-kit rlo e the joint in the beam and return the disks to their proper operative positions in tead of permitting them to routinne running too far inland. lever 28 the detent may be enga ed with the rack 25 to look the land wheel with the disks in the raised position for carrying them from place to place when not in action. It may also he need when desired to lock the then released by the link it on arranged to rotatively joint in the closed position, and a eeat and a disk supported on the respective members.

A riding plow comprising a beam. a seat movable laterally in relation thereto. a crank axle j'onrnaled on the beam and provided with a le\er, and a spring arranged yieldingly maintain the lever with the axle in predetermined rotative posi tions, said spring. being also arranged to yieldingly maintain the seat in a predetermined position in relation to the beam.

t. in a riding plow. the eonibinntit'ni ol a beam provided with a lateral break joint. a rrank axle journaled thereon and provided with a land wheel, a lever secured to the axle. and a spring; attarhed to the lever and none the axle and also to clone the joint. I

5. in a ridinp plow. the rnltlbillitlltlll of a beam provided with a lateral break joint. means l'or autoinatirall closing the joint. a seat rarr'n-d by the beam and rearwardly ot' the joint. a rranlc axle journaleti beam in front of the joint and provided with a land wheel. and a spring arranged to lnrn the axle and to simultaneously reinforee the ai'tion ot said means in closing the joint.

ii ln a .riding plow. a caster wheel. a beam having one of its ends supported thereby and provided with a wait and with a hiteral break joint. automatic means for yieldeutting depth if desired.

My improvement may be applied with equal advantage to a riding plow having either one or a plural number of disks. or to a plow wherein the ordinary shares and mold boards are used instead of disks.

Having lullv dearribed my im n'ovemem what i ('laim a mv invention and desire to secure. by'lmtters latentof the lnited States is:--

1. A riding plow comprising: a beam. a Seat movable laterally in relation thereto. a (rank axhfli urnal d on the beam and po \ided with a trronnd wheel. and a pring arranged to vit-hlingzly maintain both tho seat uml the axle with the ground \v n'el in predetermined positions.

2. In a ridin; plow. the ron'ibinali n fit a beam consisting ottwo membew. a hinge joint eounerting' them together. a spring; arranged to move and yieldingly maintain the inglv maintaining the joint furrow opener secured to the beam on the opposite side of the joint from the wheel.

T. A riding plow comprising a bea a member hinged thereon and provided with a seat. a erank axle journaled on the beam and provided with a ground wheel. and a spring' arranged to imultaneou ly turn the axle and move the hinged member with.the seat laterally in relation to the beam.

o. in a riding plow. the tt ltll)llli\llt)ll of a beam ronsi tin 1 ol two members. a joint roum-eting said members together. a rrauk axle journaled on one of said members and pro \lded with a ground wheel. a HLttll supported on aid other member. amt spring actuated inerhanism arranged to vieldingly resist the lateral movement ot' the member witlrthe mat. and to .-inn|ltaneousl v resist the turning of the axle [or raising the wheel.
